The Fast Ethernet Switch is an Ethernet Fiber Switch which is specially designed for network monitoring. It has 2*10/100Mbps Ethernet ports and 6*155Mbps fiber ports. It adopts RTL8309N chips to ensure low power consumption and high stability. It extends the transmission distance of a network from 100m to 120km via copper cables. It can extend the transmission distance; there are also many other advantages such as isolation protection, good data security, working stability and easy maintenance.
